Abstract: A sample introduction system is described that provides temperature-controlled handling and transfer of a sample from an autosampler, through a transfer line, to a heated environment proximate an analytical device. A system embodiment includes, but is not limited to, an autosampler including a temperature-controlled deck to support one or more sample containers; a heating unit including one or more heating elements to one or more fluids to be introduced to a sample removed from the one or more sample containers; a transfer line fluidically coupled with the autosampler and including a heating element configured to transfer heat to fluid flowing through the transfer line; and a sample handling system fluidically coupled with the transfer line and configured to fluidically couple with an analysis device, the sample handling system including a housing and a heating element configured to control a temperature of an environment defined by the housing.

Abstract: Rotary valve systems with integrated sensors are described that facilitate stabilizing electrical connection from a valve actuator. A valve system includes a rotary valve comprising one or more ports configured to receive one or more fluids. The valve system further includes an actuator attached to the rotary valve, wherein the actuator comprises a power connection fed from electronics associated with the actuator. The valve system further includes an actuator cap attached to the actuator, the actuator cap configured to allow the power connection to pass through, wherein the actuator cap comprises one or more apertures, a valve collar with an integrated press-on connector configured to be attached to the actuator cap, wherein the valve collar comprises an electronic feedthrough passage for the power connection, a retainer portion comprising one or more retainer pins, wherein the one or more retainer pins are configured to mate with the one or more apertures on the actuator cap, the retainer portion configured to allow electrical connection between the power connector and a sensor connector when the one or more retainer pins fit within the one or more apertures on the actuator cap, and a sensor housing adjacent to the rotary valve and configured to support one or more sensors disposed with respect to one or more fluid lines coupled to the one or more ports of the rotary valve, the sensor connector configured to transmit signals from the one or more sensors to the actuator.

Abstract: Systems and methods for automated cap removal with an autosampler system are described. In an aspect, an autosampler system includes, but is not limited to, a sample rack; a sample vessel stabilizer configured to transition the sample rack between a load/unload state and a lock state; an uncapper supported by a first z-axis support; and a sample probe supported by a second z-axis support, wherein the uncapper is configured to remove a cap from a sample vessel held by the sample rack when the sample rack is in the lock state, and wherein the uncapper is configured to change the position of the removed cap to permit access to an interior of the sample vessel by the sample probe without removing the sample vessel from the sample rack.
